Geological Summary

Pengchiahsu is one of five small Pleistocene volcanic islands NE of Taiwan. The summit of the andesitic island (also known as Agincourt) reaches only 129 m above sea level. The age of volcanism is considered to be Pleistocene, but it was reported to display fumarolic activity (Volcanological Society of Japan, 1971). However, there are no more recent reports of fumaroles or other indications of ongoing unrest as of 2015, and the Central Geological Survey makes no mention of them, though it does for other locations.

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.

WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.
